Can you post some code showing your attempt so far? What features are you having problems with?

Sorry for my first attempt to ask a question here. I have some experience with creating simple graphs with tikz for my thesis. My problem creating this diagram is that I could not find code examples of similar diagrams. In particular for creating the multiple annotations with arrows and creating the boxes. I will try to create a minimal myself. Thank you for your quick response.
